A UNIFIED MODEL FOR REAL-TIME DATA GRIDS SUPPORTING DISTRIBUTED SCHEDULING OF JOBS

摘要

There exist a number of simulators, emulators, andrnproduction platforms in the literature proposed for Gridrncomputing. Each of them assumes different models;rnpresents and supports their own list of functions. Yet, inrnthe literature, there is no unified model that thoroughlyrnand clearly describes as to how the services related to arnreal-time Data Grid system should be structured. Thisrnstudy aims at proposing a real-time Data Grid model thatrnunifies four essential components (job scheduling, datarnreplication, data dissemination and advance reservation)rnbased on a set of well-defined services. The proposedrnreal-time Data Grid model is unique and it is shown thatrnhow it can be used to build the future Data Grid systems.
